Be. it known that ll, CHARLES A. Harsnar,

a citizen of the United States, residin aty Richmond, in the county of Wayne, tate of llndiana, have invented a new and useful Automobile Lock, of which the following is a-full, clear, and comprehensive specilication and exposition, the same being such as will enable others to make and use the same with exactitude. y

The object of this present invention, broadly stated, is to provide means lor intentionally preventing the functioning of mo-v tors, especially the motors of automobiles, but stillpermitting the motor to be operated by an authorized person when desired.

More particularly stated, my object is to provide means whereby the custodian of an antomobile or the like may close and lc'k the exhaust, thereby' preventin the operation ot the motor by an nnaut orized person, as it is well hnown that a motor can not function if the exhaust be closed.

@ther objects and articular advantages of the invention will e brought out in the course of the following description, and that which is new will be correlated in the claim. 'llhe referred means for carrying out the princip es of my invention in a practical and an eilicient manner is shown in the accompanyin drawings, in which-Figure l is a side e ovation of my construction as attached in operative condition in connection with the exhaust manifold of a motor. Figure 2 is a plan view of the same. Figure '3 is a central sectional view taken through my device.. Fi ure t is a detail edge view ot the valve siuttcr and a portion ot its stem. Figure 5 is a plan view of the upper disc alone. Figure 6 is a plan view ol the lower disc alone. Aand Figure l is a side elevation of the discharge end portion of an exhaust manifold prior to the 'installation of my invention therewith.

Similar indices denote like parts throughout the several views. ln order that the construction, the operation, and the advantages of my invention may be moreA tally understood and appreciated, ll will now take up a detailed description thereof, in which l will set forth the same as fully and clearly as l may.

ln the drawings letter l denotes the usual exhaust manifold or an explosion motor, havin its dischar 'e end provided with threads a. Letter denotes the 'exhaust pipe leading from the manifoldy A to the mumer (not shown). Said ipe B is .pro

vided with the coulving C, w ich is adapted \to be run on the t reads a, as shown.

The dotted lines D designate the approximate location of thegear case orl some other relatively stationair element.` Letter E denotes the toe-boar forming Va part of the floor of an automobile with which my device is connected. And letter F denotes a paddock, or other locking means. All of the above parts are of ordinary convstruction and they may be variously changed, and are not parts of this invention.

My invention proper consists primarily of a butterdy valve, comprising the body portion Lone end of which is provided with the exterior'threads 2 which are adapted to ermit the lcouplin C to be run thereon.

he other end of t e body l is interiorly p threaded to receive the threads a., g lt, of course, is to be understoodthat there is a paSsae-way 8 through the body l which correspon s with the passage-ways through the manifold A and the pipe B.'

Numeral t denotes the valve-stem, which is integral with the body i, and it projects at right-angles therefrom. 4

Formed integral with the outer end ol the stem d, and extending out therearound, is the inner disc 5, the same being parallel with the body l and the pipe B. Formed through the disc 5, near the periphery there# ol, are the two round apertures 6 and Secured in and extending out from the lace of the disc 5 is the pin v Numeral Qdenotes the upper vor outer disc, it being of the same diameter as the disc 5. A. segmental notch 10 is formed in the peripheral portion of one-quarter of the disc 9, as is shown in Fig. 5. Also an aperture 13 is formed through the peripheral portion of the disc 9, which may register with apertures 6 7. Said disc 9 'should he formed of very hard metal or the lilre. la shaft aperture or bearing lll is formed concentrically through the stem t and the dise 5, and a corresponding aperture is formed through the disc 9, to receive the lshalt l2, which latter is revolvable in said aperture 1l, but the disc 9 is rigidly secured to the shalt 12 whereby it will revolve therewith. Means for turning the shalt l2 manually is provided bythe cross-bar la which is disn posed'through the upper end portion ot the shalt la.

to form-the slot which is of the same' width as is the thickness of the valve shutter 16 which is located therein. Numerals 18 and 19 denote rivet-s by which the valve shutter 16 is rigidly secured to the shaft 12.

In assembling the device the disc 9 is first secured on the shaft 12 (or it may be integral therewith), the valve shutter 16 is 4placed in position in the passageway 3. The

shaft 12 is then pressed down through the steni 4, striding the valve shutter 16 and with its lower end operative in the bearing 17. The rivets 18-19 are then driven in 'and riveted to retain the valve shutter in place. Now with the insertion of the cross- -bar 14 the device proper will be in assembled condition.

In order to place my invention in operaltive posit-ion I first remove the pipe B and the coupling C from the mainfold A. I then bring my device to position and cause the threads a to enter the interior threads of the body 1, which by turning the device will cause a tight joint to be formed. I next replace the pipe B by bringingit to the outer (rear) end of the body l and run the coupling C on the threads 2. In practice the stem 4 should extend through the toe-board E so that the disc 5 will be thereabove.l It is to be understood that my device is to be connected with the manifold A before the device and the manifold are placed in position in the machine, as the device can not be turned after the manifold is secured in place on account of the gear-case D.

It. is now quite evident that ifthe valve shutter 16 be turned edgewise in the passageway 3 that the exhaust may pass from the lnanifold A out through the pipe B as before, this position being shown in Fig. 1, at which time the apertures 13 and 6 will register with each other, permitting the shackle of the lock F to beinserted therethrough wher-eb the device may be locked against being c osed. p

Now desiring to lock the device I first remove the lock F and then by grasping the bar 14 I give the shaft 12 a quarter turn, that is turning the pin 8 from one to the other extreme of the notch 10. This' will cause the valve shutter to extend across the passageway 3 thereby preventing the escape of the exhaust therethrough. Then by placing the lock again in securing position, that is inserting its shackle through the apertures 13 and 7, which are then in register with each other, it is evident that the exhaust Will be locked and -the motor-can not be operated until the valve shutter has been turned to open position, thereby accomplishin the desideratum of this invention.

aving `now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, is

An automobile locking means comprising in combination with an exhaust manifold, a body adapted to be secured to the discharge end of the exhaust manifold With a passageway therethrough forming a continuation of the passageway through the manifold, a stem rotatably mounted in said body and extending out therefrom at right angles thereto, arvalve shutter carried by said stem and adapted to be turned in said passageway in the body to open --and close said passageway, a disc integral with said body and concentric of the stem, a second disc rigidly connected with said stem and contacting flat with the first disc, there being apertures formed through both of said discs with the apertures of one disc adapted to register with the apertures of the other disc, a padlock Whose shackle is adapted to be inserted in two of said apertures when they register with each other, means whereby said stem may be turned manually', and means for limiting the rotation of the stemin either direction, all substantially as shown and described.

CHARLES A. HAISLEY.
